Thanks for the reply! I definitely agree - the ability to develop quickly I feel was the main reason it was used when I worked with developers in the past who were using Bootstrap, and likely a part of the interest in using it again.

I didn’t realize that Bootstrap used negative margin so much - I’ve had to use it in the past myself for general explorations into CSS and I never did like it. I’ve heard a lot (and seen a lot) about CSS Grid, but I’ve never had an opportunity to use it. I think that might be the next thing I look into!
